Alessandro Volta (1745–1827) is credited with the discovery of the construction and design of the first electric cells. The name voltaic is often used to describe the type of cell you will study in this module. One type of voltaic cell design uses copper and zinc electrodes. This type of cell is often studied due to its reliability.

No fast forward to today, batteries are used in any mobile device, from your cell phone to tablets, even to power tools and pace makers that keep your heart pumping. These batteries are divided up into two major groups, dry cells (i.e. Lithium-Ion or Alkaline batteries in your mobile devices) or wet cells (i.e. Lead-Acetate battery in your car). But this sort of technology has reached its design limit and newer better ways are being researched and developed for the next generation of longer lasting, cheaper, safer batteries. Below are three varying ways battery technology is being developed.
Todays Technology Solar Electric Battery Powered and Wind Power Passager Van that an individual tells about building himself. You may laugh at first until you realize the sort of range (mileage) he gets with his yellow van.
Stanford University Professor Hongjie Dai and colleagues have developed the first high-performance aluminum battery that’s fast charging, long lasting and inexpensive. The flexible, non-flammable device produces 2 volts of electricity. The research team was able to generate 5 volts - enough to power a smartphone - using two aluminum batteries and a converter.
Uppsala University in Sweden have designed a new battery that recharges extremely quickly and weighs almost nothing. The secret: common pond algae.
